Ukugaya i-grinder engenasikhungo

Ukugaya okungenamaphakathi:

Umshini wokugaya ongenalutho umshini wokugaya ojwayelekile, owaziwa nangokuthi umshini wokugaya oyi-cylindrical. Ukusetshenziswa kwayo okuyinhloko kusembonini yokukhiqiza amathuluzi omshini, asetshenziselwa ukucubungula izinhlobo ezahlukene zezingxenye ezincane ze-batch shaft, kuhlanganise nejenali, i-chain shaft, ukulungisa ukumpompa, njll.

Izici zokugaya ze-grinder engena-centerless:

Umshini wokugaya ongenalutho ungafinyelela ubulukhuni obusezingeni eliphansi, ngokuvamile ungafinyelela ukunemba kobukhulu be-T6 ~ IT, futhi ubulukhuni obutholakalayo bungu-Ra125 ~ 0Oum; Ubunzima obungaphezulu bokugaya okuphezulu nokugaya kwesibuko bungafinyelela ku-Ra0.05um.

I-2, umshini wokugaya ongenalutho ungagaya zonke izinhlobo zensimbi ecishiwe, insimbi eshisayo ye-alloy kanye ne-alloy eqinile nezinye izinto ezinzima.

I-3, umshini wokugaya i-cylindrical ongenamaphakathi wokwenza ukucubungula. Ngenxa yokuthi isondo lokugaya lingasikwa libe yizimo ezihlukahlukene ngokuvumelana nezidingo zomshini, kuyadingeka ukugaya umumo oyinkimbinkimbi kafushane. Kusetshenziswa kakhulu ekugayeni ifomu ukuze kuncishiswe inqubo emaphakathi.

I-4, i-centerless grinder yokugaya i-margin incane kakhulu, ifanele ukuphonswa, ukufakela, ukugxiviza izingxenye zokucubungula okulandelwayo, ukuze kuthuthukiswe ukunemba kwezingxenye ezingenalutho, ukunciphisa ubulukhuni obungaphezulu.

I-5, umshini wokugaya ongenalutho ulungele imishini ezenzakalelayo, ungathuthukisa inqubo yokugaya.

Okokuqala, amandla okugaya

①. Umthombo nokubola kwamandla okugaya

Kukhona amandla alinganayo futhi aphikisanayo asebenza esondweni lokugaya kanye nendawo yokusebenza ngesikhathi sokugaya. Amandla akhiqizwa inqubo yokugaya abizwa ngokuthi amandla okugaya (amandla okusika). Amandla okugaya ngokuyinhloko akhiwe izingxenye ezimbili: okusanhlamvu kwe-abrasive kuzobangela ukuguqulwa okukhulu kwepulasitiki yensimbi ukuze kunqunywe lapho kusika insimbi, futhi amandla okusika akhiwa; Amandla okugaya akhiqizwa phakathi kwezinhlayiya nendawo yokusebenza ngesikhathi sokusika.

(2) Ithonya lamandla okugaya emishinini

Ekugayeni, izinhlayiya zokugaya zisikwa nge-Angle yangaphambili engalungile, futhi i-fillet radius R yonqenqema lokusika ivame ukuba nkulu kunenani lokusika emuva, ngakho-ke ukucindezela kwe-radial yokucindezela kwezinhlayiya zokugaya ku-workpiece kukhulu, ngokuvamile i-Fp = ( 2 ~ 3)FC. Ngenxa yamandla amakhulu e-radial, uhlelo lwenqubo olwakhiwe ithuluzi lomshini, i-workpiece kanye nesondo lokugaya lukhiqiza ukuguqulwa okukhulu kwe-elastic, okuthinta ukunemba kokugaya. Uma i-workpiece ikhubazekile ngenxa yesenzo samandla e-radial namandla e-tangential, ukunyakaza okuhlobene kwe-eksisi yayo ngu-e, okuzodala iphutha lobubanzi bomsebenzi wokusebenza.

Ukuguquguquka kwesistimu yenqubo okubangelwa amandla e-radial ngokuvamile kwenza inani langempela lokusika emuva lihluke kunani lesihlahla eliboniswa ekudayileni okuphakelayo kwamasondo. Ngakho-ke, umjikelezo wokugaya ofanele ukuma ngemva kokuphakela ukuze kuqedwe ukuwohloka okubangelwa amandla e-radial. Lolu hlobo lokugaya ngaphandle kokuphakela kubizwa ngokuthi ukugaya okulula noma ukugaya okungenanhlansi. Lapho ugaya i-shaft ezacile, ucezu lokusebenza lugaywa lube yisimo sesigubhu ngama-radial force. Izici zesondo lokugaya, ububanzi bokugaya isondo lokugaya, impahla yokusebenza, inani lokugaya (ap, f) linethonya elikhulu kumandla omsakazo.
